ABSTRACT
The main objective of the Marine Strategy Framework Directive (MSFD, 2008/56/EC) is to achieve or to establish and maintain the "good environmental status" (GES) until 2020. The Black Sea is one of the fourth marine regions assigned for implementing the MSFD through two countries and EU Member States: Romania and Bulgaria. Through the MSFD Guiding Improvements in the Black Sea Integrated Monitoring System (MISIS Project), for the Romanian waters were defined and delimited the types of the seawater. Using the short and long-term data analysis of the physical parameters (temperature and salinity from available data since 1955 – 2012), the main features of the western Black Sea water bodies was characterized. In addition, the corresponding salinity of water bodies in the western Black Sea were evaluated, using the grid points 0.5° x 0.5°, calculating for each quarter from the corresponding number of measured data: the mean, standard deviation and the coefficient of variation. Based on the physical parameters, the degree of anthropogenic impact, chlorophyll-a concentration, bathymetry etc., four categories of the Romanian Black Sea waters types were identified: RO-TT03 – the northern part, marine waters under the direct influence of the Danube, at depths of at least 30 m; RO-CT01 – the marine waters from the central to the southern area (Portita down to Vama Veche), from the baseline to 30 m isobath; ROMT01 – that corresponds to the inner and the outer shelf marine area from the 30 m to the 100 m isobaths and RO-MT02 – the perimeter for the type of offshore seawater located at depths of at least 100 m.
